Re; Not due to air pressure

I'm sorry, did you just say that the Mythbusters disproved something? Yes, of course, what with their rigorous, dispassionate scientific investigation that had nothing at all to do with television sensationalism.

I'm sure they fired rifle bullets into the fake tits and replayed it in slow motion, or something. I'll bet they even found an excuse to visit the aircraft boneyard.

Erm...

Old news

The report may be new, but the concept has been applied all over the place.

The American space program has used various treadmill modifications (elastic tethers, negative pressure* waist cuff things, etc) and the Russians had a "penguin suit" which applied force against the limbs throughout the day.

The problem isn't technical. The problem is compliance. The solutions are tedious and uncomfortable to use.
